Asteroseismology: Observing Stars Vibrate with CoRoT
Observing a stars brightness pulsate may reveal its internal structure say researchers using the Convection Rotation and Planetary Transits (CoRoT) observatory. The highly sensitive orbital telescope can detect tiny variations in a distant star's brightness, leading astronomers into a new field of stellar seismology called "asteroseismology." Seismology is more commonly used by scientists on Earth [...]

Real-time solar storm warning now operational, protecting astronauts and satellites
Highly energetic solar particles are generated by solar flares and can be harmful to astronauts and sensitive satellite circuits. Solar flares are most likely to occur during periods of heightened solar activity (i.e. during solar maximum at the peak of the 11 year solar cycle), and future manned missions will need to be highly cautious [...]
